Do asexual people enjoy kissing?
Some asexuals enjoy kissing, and some don't.
Kissing may or may not be considered a romantic or sensual gesture (rather than a sexual one), meaning that some asexuals might be attracted towards kissing others. Such feelings do not necessarily imply sexual desire.
Separately, similar to sex-repulsion and -favourability, an asexual person (or indeed any person) may enjoy the sensation of kissing without experiencing any intrinsic urge to kiss any particular people.
